1. INSTALL MOTOR CAPACITORS
Electric motors generate radio noise that can cause
radio interference. Included are three 0.1
µ
F (50V)
non-polarized, ceramic capacitors. These capacitors
must be installed on every motor to help reduce
the noise generated by the motor and also to
prevent possible damage to the speed control.
Solder 0.1
µ
F (50V) capacitors between:
• POSITIVE (+) motor tab & NEGATIVE (-) motor tab.
• POSITIVE (+) motor tab & GROUND tab*.
• NEGATIVE (-) motor tab & GROUND tab*.
*If your motor does not have a ground tab, solder the ca-
pacitor leads to the can of the motor as shown below.
Negative (-) motor tab
0.1
µ
F Capacitors
Schottky diode
Positive (+) motor tab
Ground / motor can
Extra 0.1
µ
F capacitors are available in Novak kit #5640.
2. INSTALL SCHOTTKY DIODE
(if required)
Consult your speed control’s operation manual to
determine if an external Schottky diode is required.
Use of an external Schottky diode
(even if your ESC
already has one in it)
will increase the efficiency and
reduce the operating temperature of the ESC.
NEVER USE A SCHOTTKY WITH A REVERSIBLE ESC
• Solder the lead
CLOSEST
to the silver stripe on
the Schottky diode to the
POSITIVE (+)
motor tab.
• Solder the lead
OPPOSITE
the silver stripe on the
Schottky diode to the
NEGATIVE (-)
motor tab.
Schottky diodes are available in Novak kit #5640.
3. CONNECT STEERING SERVO
After the proper input plug plastic has been installed
on the steering servo
(Refer to Step 2)
, plug the servo
into channel 1 on the XXL.
4. CONNECT SPEED CONTROL OR THROTTLE SERVO
After the proper input plug plastic has been installed
on the speed control or throttle servo
(Refer to Step 2)
,
plug the speed control or servo into channel 2.
5. OPTIONAL USE OF EXTERNAL BATTERY PACK
A 4 or 5-cell external receiver battery pack can be
used if erratic radio operation is experienced during
hard acceleration. Consult your ESC’s operation
manual for proper installation and usage.
The external battery pack’s plug inserts into the XXL
with the
positive (+)
wire in the
middle
and the
negative (-)
wire towards the
outside
edge of the case.
STEP 4
HOOK-UP INSTRUCTIONS
Servo And/Or Speed Control Does Not Work
• Make sure steering servo is plugged into
CH.1
of receiver
and throttle servo or speed control is in
CH.2
.
• Check color sequence of input plugs––Refer to Step 2.
• ESC or electronics are not connected to battery pack.
• Check wiring and connections.
• Bad receiver and/or transmitter crystals––Check with a
different set.
Receiver Glitches/Throttle Stutters On Acceleration
• Motor capacitors broken or missing–Refer to Step 4.
• Receiver or antenna too close to speed control, power
wires, battery, or motor––Relocate receiver.
• Bad connections––Check wiring and connections.
• Motor brushes worn––Replace brushes. Motor may also
be worn and need to be rebuilt.
• Excessive current going to motor––Use a milder motor
or a smaller pinion gear.
• Bad receiver and/or transmitter crystals––Check system
with a different set.
• Voltage to receiver is too low––Try using an external re-
ceiver battery pack. Refer to Step 4.
• Possible internal damage––Refer to service procedures.
TROUBLE-SHOOTING GUIDE
FCC APPROVAL NOTE
This equipment has been tested and found to comply with the limits for a
Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in
a residential installation. This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and used in accordance with
this instruction manual, may cause harmful interference to radio commu-
nications. However, there is no guarantee that interference will not occur
in a particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning the
equipment off and on, the user is encouraged to try correcting the inter-
ference by one or more of the following measures: (1) Reorient or relocate
the receiver’s antenna; (2) Increase the separation between the equipment
and receiver; (3) Consult an experienced radio/TV technician for help.
